A drunken, whoring layabout mortal-turned particularly vicious vampire 200-plus years ago. "For 100 years I offered a violent death to everyone I met, and I did it with a song in my heart." His comeuppance came in 1898, after he killed the favorite of a Gypsy clan; they cursed him with the return of his soul and conscience (a drawback for those who suck blood for a living). After falling in love with Buffy the Vampire Slayer and losing his soul briefly in Sunnydale, Angel moves to L.A. to atone for his multitudinous sins, to save souls one at a time, and perhaps in the process, his own. He now guards "his town" the City of Angels, Los Angeles-- with the help of Cordy, Wesley, and Gunn. His biggest hope has been promised in the prophecies, that his redemption will be to "shanshu", to live and die, to become human. Part of this from EW
Buffy Season One
Mysterious background guy...
"You have no idea what it's like to have done the things I've done... and to care."
Buffy Season Two
Half of the forbidden romance that turns deadly...
"I love you. I try not to, but I can't stop."
"She made me feel like a human being. That’s not something you just forgive."
"My friends, we're about to make history... end."
Buffy Season Three
Back to background blending and feeling guilty...
"Look, I'm weak. I've never been anything else. It's not the demon in me that needs killing, Buffy. It's the man."
"You'll always be a Slayer. But that's all the more reason why you should have a real relationship instead of this.”
"I'm not going to say good-bye. If we get through this... I'm just going to go."
Angel Season One
Gets his own show. Doing pretty well....
"You looked lonely. And I figured that we have something in common."
"You never know your strength until you're tested."
"In case you've forgotten, we're not in the business of giving up on people."
"The vampire with a soul, once he fulfills his destiny, will Shanshu. Become human. It's his reward."
Angel Season Two
The road to redemption is a rocky path filled with deep ditches...
"I've come to help you. My name is Angel."
Holland: "Angel, please. People are going to die."
Angel: "And yet, somehow, I just can't seem to care."
"It doesn't matter. None of it matters."
"If nothing we do matters, then all that matters is what we do. 'cause that's all there is... Because, if there is no bigger meaning, then the smallest act of kindness - is the greatest thing in the world."
"We know you. We know you're a man with a demon inside, not the other way around. *We* know you have the strength to do what needs to be done, and you will come back to us."
